Dish takes over what remains the country's largest brick-and-mortar video rental chain, though it has shut down thousands of stores to reach the current total of 1700. One factor in its downfall was the huge debt load it took on when Viacom spun off the company in 2004. As recently as 2009, Blockbuster was confident (if not actually robust) enough to bid a cool billion for Circuit City. Now its share price has dropped so low, it's been delisted from the NYSE.
